Application filed June l5, 1903. Serial No. 161,559 (No mmh .To @ZZwiz/om, it nto/y concern:

lie it known that l, lflLnAZnn Hnnrsnixml, a Citizen ol theUnitedStates, residing in Boston, in the eounty el.' Suilfolk and Stateof Massaehusetts, have invented certain new and useful lniprm'ennnits in(ifolflalis, oli` 4which the 'following' a speeilieatiou.

This inrenl ion relates to golf-balls; and i1' objeet is principally toinerease the driving` power or ilying eapability'ol the ball.

A .further objeetis to Jnrodueea ball ofgrea-t driving,I lpower whoseweight shall conform to standard. i

A :further object is to provide a ball having a suilieiently elast-ieinterior to givelthe ball the desired. flight without rom'lering theshell lliable to bursting.

In the accompanying drawings, Figure 1 is a sectional View of a i, allmade in accordance with my presant improvements. Fig. is an elevationalView, upon anenlarged seale, oi' a fragment o1. the ball.

In the views' like signs denote like parts.

Upon the ee] `ter piece1,1)referablyof getta` pereha, l wind 'inmiseellaneous directions a thread of fine-eln'ed--rubberthread undertension to `forni a sphere 2, the diameter ol which is preferably oneineh, although it-inaj.7 be a trifle greater or smaller. The eente1.'pieee l may be olnittei'l and the entire sphere 2 may consist ofwindings el.' the thread. l

lt will be understood that throughout the sphere thereoeeu r innumerableinterstiees,

vas indieated at 3, and these intel-sticos make it possible for thissphere, Considered as a whole, to be compressed sl ightly in bulk. whenthe ball is given a blow, owing' partly to the interstiees and of therubber thread .v lt is also possible l'or the sphere to be locallycompressed at any point to an appreriable degree.

partly to the nyielding nature cured rubber-that is, rubber which hasbeen ebanged from a crude to a usable state by a Well-known aeid professand whieh van be drawn extremely thin and withstauds great strain. lhislayer is solid throughout, the solid ity being;` eileeted by thethinness to which the sheeting is tensioned, in eoinbinathm with theliam'l-paeking' aetiou due to the tf-nseness oli' the 'windingsthemselves, whieh it will be understood paeks the layers in a mostol'lfmiet nal manner. Owing` to the solidity olf the layer thus formed',all parts of which are under great tension, (preferably considerably`greater than the tension o l' the rubberthreml whieh ifo-ruis thesphere 2,) lateral flow of the rubber shell or strip beeomesinipossible, and heuee any further distortion of the rubber when ltheball is struek can oeeur ina direction longitudiiially oi thehighly-tensioned strips.v lloreover, this layer 5 is so hard andso hight)Y tensioned as not to be duly ai'lerted by a light blow, remleringthe ball excellent for putting. This sheeting l wind eentinuous inmiseellaw neous direetions, layer over layer, in suoli a manner as tomake the ball solid throughout I prefer to use sheeting originally fromnine one thousa-inlths to twelve one thousandths of au inch in thicknessand tensioned to an extent to reduce suoli thiekness to lroni threeone-thousaudths to four onethousandths oi' an inell. st1uek,tl1e forceis transmitted from the gottapereha shell through the tense rubber layer5to the highly'elastie but eompressible inner rubber-thread sphere 3, bythe yielding Ywherroif two results are accomplished. The 4 lirstconsists in tlie'reaetion of said sphere 2, whereby the Hight el' theball is aided, and the seoond consists in the prevention of theburst-ine' oll the gutia-qiereha shell l. In rel erenee to bursting' itwill be understood that beeause ol the solidit)v oi.` the layer or shell5 auby ehange in the forni thereof lrodueed by :t blow inermi-sestheisupi-niioial area of the sphere 5, or, in other words', tends tosireteh alulburstopentheffutta-perehashell.(i. New by hari ug withinsaid shell :3 a ruliber-thrinul sphere 2 which is l'ullofinterstiees thelatterby reason. el' its eonipressibility may yield Sullieie n lily totake up the expansive pressure oi the solid layer 5 when it is streek,so that the latter may have opportunity to expand inwardly l'Vhen theball isl ICO sion of `thisl bodily-uoinpressible throiutlill-v ing forthe rubber shell the letter hes more room for distortion, and henee morelinneo t0 reitet upon theI elub while the ball. is in eontztcttherewith, the eby further ii'iorensinf.; the liying power of the ball.

It is found by testing` that the wein-ht nl' ai shell consisting oftensioned Yrubber ihreznls, :is 2, is less then the .veigl'it of n,similar shell mede of pure sheeting", es employed in the lei-yor so thatby my eonstrnetion the weight of the bnll is mede less than when thefilling' Consists throughout of :wid onred rubber sheeting, so that thesphere 2, which prefer-- ablyoeeupies more than hnlli' the diameter ofthe bell., is ot less specific gravity the-n the outer portion of thebell, which is it desiderttum, as it produces n tendeney to prolong theflight of the ball when it is skilt'nlly strnek.
